JSF components and utilities that can be used with any JSF implementation. This library is based on the JSF1.1 version of Tomahawk, but with minor source code and build changes to take advantage of JSF2.0 features. A JSF2.0 implementation is required to use this version of the Tomahawk library.

The newest version!

// Loggers
//
//  Loggers are pretty simple classes, that should have 1 method, called 
//  'log'. This is called with 2 arguments, the first one is the message to
//  log and the second is the severity, which can be 0 or some other false
//  value for debug messages, 1 for warnings and 2 for errors (the loggers
//  are allowed to raise an exception if that happens).
//
